  • 074ccf801   [PATCH] mm/Kconfig: kill unused ARCH_FLATMEM_DISABLE ... Browse Code »

    This used to be used to disable FLATMEM selection, but I decided to change it
    to be done generically when DISCONTIG is enabled. The option is unused, so
    this kills it.

  • 0e19243e9   [PATCH] update all defconfigs for ARCH_DISCONTIGMEM_ENABLE ... Browse Code »

    This will at least suppress one prompt that users would have received the
    first time they compile with the new DISCONTIG arch option. They'll still
    get the "Memory Model" prompt, but 99% of them will have the default work
    there.

  • 3f22ab276   [PATCH] make each arch use mm/Kconfig ... Browse Code »

    For all architectures, this just means that you'll see a "Memory Model"
    choice in your architecture menu. For those that implement DISCONTIGMEM,
    you may eventually want to make your ARCH_DISCONTIGMEM_ENABLE a "def_bool
    y" and make your users select DISCONTIGMEM right out of the new choice
    menu. The only disadvantage might be if you have some specific things that
    you need in your help option to explain something about DISCONTIGMEM.

  • 408fde81c   [PATCH] remove non-DISCONTIG use of pgdat->node_mem_map ... Browse Code »

    This patch effectively eliminates direct use of pgdat->node_mem_map outside
    of the DISCONTIG code. On a flat memory system, these fields aren't
    currently used, neither are they on a sparsemem system.

    There was also a node_mem_map(nid) macro on many architectures. Its use
    along with the use of ->node_mem_map itself was not consistent. It has
    been removed in favor of two new, more explicit, arch-independent macros:

    pgdat_page_nr(pgdat, pagenr)
    nid_page_nr(nid, pagenr)

    I called them "pgdat" and "nid" because we overload the term "node" to mean
    "NUMA node", "DISCONTIG node" or "pg_data_t" in very confusing ways. I
    believe the newer names are much clearer.

    These macros can be overridden in the sparsemem case with a theoretically
    slower operation using node_start_pfn and pfn_to_page(), instead. We could
    make this the only behavior if people want, but I don't want to change too
    much at once. One thing at a time.

    This patch removes more code than it adds.

    Compile tested on alpha, alpha discontig, arm, arm-discontig, i386, i386
    generic, NUMAQ, Summit, ppc64, ppc64 discontig, and x86_64. Full list
    here: http://sr71.net/patches/2.6.12/2.6.12-rc1-mhp2/configs/

    Boot tested on NUMAQ, x86 SMP and ppc64 power4/5 LPARs.

  • cbe37d093   [PATCH] mm: remove PG_highmem ... Browse Code »

    Remove PG_highmem, to save a page flag. Use is_highmem() instead. It'll
    generate a little more code, but we don't use PageHigheMem() in many places.

  • 5cae841b1   [PATCH] ISA DMA Kconfig fixes - part 1 ... Browse Code »

    A bunch of drivers use ISA DMA helpers or their equivalents for
    platforms that have ISA with different DMA controller (a lot of ARM
    boxen). Currently there is no way to put such dependency in Kconfig -
    CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA
    slots, but have on-board devices that pretend to be ISA ones).

    New symbol added - ISA_DMA_API. Set when we have functional
    enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the
    series will add missing dependencies for drivers that need them.

    I'm very carefully staying the hell out of the recurring flamefest on
    what exactly CONFIG_ISA would mean in ideal world - added symbol has a
    well-defined meaning and for now I really want to treat it as completely
    independent from the mess around CONFIG_ISA.

  • 2fd6f58ba   [AUDIT] Don't allow ptrace to fool auditing, log arch of audited syscalls. ... Browse Code »

    We were calling ptrace_notify() after auditing the syscall and arguments,
    but the debugger could have _changed_ them before the syscall was actually
    invoked. Reorder the calls to fix that.

    While we're touching ever call to audit_syscall_entry(), we also make it
    take an extra argument: the architecture of the syscall which was made,
    because some architectures allow more than one type of syscall.

    Also add an explicit success/failure flag to audit_syscall_exit(), for
    the benefit of architectures which return that in a condition register
    rather than only returning a single register.

    Change type of syscall return value to 'long' not 'int'.
